A research team led by Professor Kaicun Wang at Peking University has released a homogenized gridded climate dataset for China (HCD01), providing daily, 0.1-degree climate data for 1961-2022. The dataset corrects non-climatic signals in long-term observations and merges homogenized station records with ERA5-Land reanalysis, offering a high-quality data basis for studying climate change and its impacts across China.

In a paper published in SCIENCE CHINA Earth Sciences, researchers assessed the parameterization of orographic gravity wave drag (OGWD) in 3-km-resolution WRF simulations for precipitation forecast over the highly complex-terrain Southwest China. Their results reveal that OGWD parameterization, previously considered negligible in kilometer-scale models, can greatly improve the predicted rainfall intensity and location by modulating the low-level winds and moisture transport. These findings lay an important scientific foundation for operational precipitation forecasting in regions of complex terrain.

Researchers from Sun Yat-sen University and Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) recently observed a species of armored searobin, Scalicus engyceros, walking sideways and backward on the sea floor in the South China Sea. This is the first time a species of fish has been observed walking backward.

For the first time, researchers have used data from narwhals to document how Atlantic water reaches deep into fjords along Greenland’s east coast. A new study from the University of Copenhagen sheds light on a poorly studied region, and the findings could have important implications for understanding and predicting climate change.

Study by University of Utah geoscientists creates 3D map of a hidden ‘rock glacier’ in the Wasatch Mountains, one of more than 800 in Utah. The team used their novel method of measuring these features to estimate the world’s 50,000 rock glaciers hold 48 cubic kilometers of water.
